yo yo effect (n) - the action of a girl or boy from a past realationship toying with your emotions. Sending signals that they want you back and suddenly being very cold to you off and on. Sort of keeping you as a back up if their current realationship or intrest fails

It's when you're pushing your girl's head in the right direction, but she's stubbornly comming back to kiss you.
Come on, I just wanna one small blow job! I had enough of this yo-yo effect stuff, gonna open a beer and watch a game.
